AEBOPLANE-BOMB.

To all 'whom t may concern Be it known that I, JosEru HILL, a citizen 'Yof the United States, residing at Windom,

`,and I do hereby declare f a full, clear,

` improve the construction of aeroplane bombs and to provide a simple,practical and eilicient aeroplane bomb adapted to carry a relativelylarge quantity of high explosives and of insuring a positive dischargeof the same.

i It is also an object of the invention to provide an aeroplane bomb ofthis character which will, when dropped from an aeroplane, accuratelymaintain its course and thereby increase the effectiveness of bombs ofthis character.

With these and other 'objects in view, the

. invention consists in the construction and aoA fas

novel combination of parts hereinafter fully described, illustrated inthe `aci'zompanying drawing and pointed out in the claim heretoappended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claim, may be resorted to withoutdepartino from the spirit orsacrificing any of the advantages of the invention.

In the drawing:

Figure 1 is a longitudinal sectional view of a bomb constructed inaccordance with this invention.

Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1.

VLike numerals of reference designate corresponding parts in the severalfigures of the drawing.

In the accompanying drawing, 1 n which is illustrated the preferredembodiment of the invention, the aeroplane bomb comprises in itsconstruction an outer shell 1 of relatively thin material provided witha tapered front or, lower portion 2 and having its upper or rear portion3 substantially cylindrical.

Y The shell or casing, which presents the configuration of a bullet orprojectile, may be constructed in any suitable manner to enable theinteriorly arranged parts to be conveniently assembled, and the saidshell,

which may be sectional, is provided at its front tapered portion with asolid projectile section 4 having a central longitudinal opening 5 whichregisters with an opening 6 in the point of the shell 1. i

Within the cylindrical opening 5 is arranged a tube 7 designed tocontain a charge of dynamite and adapted to be exploded by a cap 8 whichis discharged by the inward movement of the said tube. The upper end ofthe opening 5 is threaded to receive a threaded disk 9 which is providedwith a central tapered projection 10 adapted to form a firing pin andexplode the cap 8. The tube is provided at the lower end with a solidprojecting portion 11 which is adapted to come in contact with theground or other surface in the path of the bomb for causing inwardmovement of the tube. The shell is equipped at the opening 6 withrelatively flat springs 12 which embrace the lube and retain the same inposition within the opening 5. The springs are designed to be ofsuflieient strength to prevent accidental dislodgment or movement of thetube and they are adapt- 'ed to permit the tube to be readily foi-cedinward when the solid portion 11 comes in contact with the ground. Thesolid portion 11 and the tube constitute a plunger for The shell isprovided at the center .of its top or rear wall 14 with a blade or vane15 preferably consisting of a triangular sheet of aluminum or othersuitable material secured within a frame 16 of steel or other suitablematerial. This will cause the bomb to maintain a straight course andenable it to be dropped with accuracy. When the bomb is dropped thesolid portion of the tubular plunger will come in contact with theground or with an object in the path of the bomb and the dynamite willbe exploded and will cause an explosion of the nitroglycerin or otherhigh explosive. As the lower tapered or pointed portion of the bomb isheavier than the upper portion, the plunger will be maintained in properosition for contacting with the ground, buil ing or other object. Thetop wall 14 is provided' with a iilling opening 17 and it has a threadednitro-glycerln to be2 readil introduced lnto the upper portion of the sell but the shell ma be charged in any other desired manner,

5 an the explosive may be in any desired form.

. What is claimed is: v .A

In a projectlle, a cylindrical casm containing a main explosive charge,a ownwardly tapering solid membersecured to the lower end of said casinand formin a closure therefor, said mem rbeing rovi ed with an axialbore, a disk secure in said bore adjacent the upper end thereof andpro-v videdlwith a central downwardly directed ring pin,4 a hollowcylindrlcal detonator as to be detonated by the firing pin when forcedupwardly in said bore, said detonatorv being provided with a solid endportion rojecting beyond the solid member carrie by the lcasing, andmeans frictionally engaging said detonator for releasably securing thesame in operative position. i

In testimony whereof I 'aix my signature in presence` of .two witnesses.
